With glass taking up a large proportion of a window, French or patio door’s surface, its quality and design plays an important role in the product’s performance. Consisting of two panes, double glazing is an excellent standard option to ensure warm interiors. At windows24.com it can also be tailored to suit exact requirements, from enhanced soundproofing to safety and style. To find out more just keep reading or head to the configurator to purchase today.

The panel is finished in a microscopic low-emission (low-e) coating. Made from a metal oxide like silver, the coating reflects ultraviolet (UV) light as well as infrared (IR) radiation. This helps to keep interiors cool in summer. During winter, on the other hand, the coating reflects warmth back inside, preventing it from being lost. Because visible light has a different wavelength, its entry through the window isn't restricted, which means that interiors remain bright and welcoming.

Our glazing is securely held in place in the window sash or frame thanks to rubber seals, or gaskets, that are firmly attached to the inner and outer panes. They ensure the necessary pressure for a sturdy fit while also ensuring watertightness and preventing draughts for good, sealed insulation.

The space between the two panes is filled with sealed argon gas. This is a colourless, non-reactive (inert) noble gas, which is denser than air and so better slows energy loss through the window panel to provide good thermal efficiency.

Double glazed panels feature spacers between the panes. These can be made from aluminium, or for increased insulation, we offer options made from uPVC, or a premium composite Swiss variant. The width of the gap between the sheets also affects the thermal efficiency; we therefore offer two double glazed options, one with a better Ug value of 1.0 W/(m²K), and another with a Ug value of 1.10 W/(m²K), which features slightly narrower gaps. Between the sheets, desiccant is also used. This is an absorbent material that additionally draws away moisture to help prevent condensation.

Whether you opt for triple or double-glazed units will depend on several factors. These can include the climate, budget, regulations, the product’s installation location, and how interiors are used.
For customers living in places with more extreme climates or who aim to build certified passive houses, we would recommend purchasing triple glazing.
On the other hand, for those looking to install basement windows or standard French doors for living areas and who are not so set on maximum energy-saving, double glazing will be more than sufficient and brings good insulation.
In general, triple-glazed panels offer better insulation thanks to higher energy efficiency. This will result in lower utility bills and a more reduced carbon footprint. Due to being slightly thicker, the glass will also offer better soundproofing in its basic configuration.
Because of their enhanced construction, triple-glazed units tend to come with a higher price tag and windows are slightly heavier to install.
To add character and interest to interiors and exteriors alike, a range of ornamental glazed finishes like the textured Cathedral Small or Master-Carré® can be used. On the other hand, to best shield interiors from onlookers and to add seclusion, a frosted type like Chinchilla is also available.
Double-glazed units can additionally be professionally treated during production to increase their impact resistance and alter the way in which they can break. The processes include tempering, where the panel is heated to a very high temperature before being rapidly cooled, as well as lamination, where invisible PVB foil interlayers are inserted.
These treatments make the glass tougher and increase pressure deflection, giving windows increased break-in protection and making them ideal for customers with properties in high wind zones or coastal areas. Moreover, if the panel does crack under high force, then it won’t break into sharp shards. Rather, blunt crumbs will form, or the pieces will remain held on intact foil beneath.
Our window and door glass can also be purpose-designed to provide the desired degree of sound protection. This can be ideal for buildings located near busy roads, for example.
To add noise reduction, an invisible “silence foil” is added. This slows the travel of sound waves by different extents. For maximum soundproofing, we offer glass aligning with sound insulation class 5, which reduces noise by 45 dB and can insulate homes located as close as 300 m from an airport.
